Angel, I had to take a "break" on two ocassions. The first was to put in a feeding tube as my mouth was so messed up. Second was toward the end of tx. My RO pushed to get me back in as soon as possible but never expressed concern about these delays ( one was for a week and the second was 4 days ). I personally think you can take this off your worry list.
